I went to windows 11 and yes, I've had a lot of issues with it. I had to have some extensions removed so now I can't just pull up a file with my quilting patterns and look at them, I have to take them into a program to see what they look like. Luckily, this didn't bother my embroidery designs.
As for resizing photos, I just double click the photo and then click on "edit" at the top left corner to crop it and any other changes I need, then save it. I click again on the photo and go over to the 3 dots to the right at the top and that's where it allows me to resize it. Once opened, there's a spot called (quality) with a lever you can move from side to side and if you watch down below, it will give you number of pixels, Also right alongside of the "quality" you can change the type of photo it is too. I find "jped" gives you the smaller size.
